BMW M135 (F70) Performance Exhausts

Our sports exhaust upgrade for the BMW M135 has been designed as a quad exit valved GPF back exhaust setup. Expertly TIG welded by hand in Sheffield, UK. Our performance exhausts range is fully guaranteed to give you assurance of our quality, offering improvements in terms of exhaust tone, bass and sound level whilst keeping the stock catalyst and GPF in place. The latest BMW M135 keeps the winning recipe intact — a 4WD chassis, just over 300bhp, and the familiar 2.0-litre turbocharged engine. The styling may be refreshed, but beneath the surface it’s every bit the performance hatch enthusiasts have come to love. The only drawback? A factory exhaust note that doesn’t quite match the car’s potential. That’s where Cobra Sport stepped in. Engineered to match the M135’s premium feel, our valved GPF-back, direct-fit exhaust system integrates perfectly with the OEM value layout, retaining full emissions compliance while unlocking a richer, more engaging soundtrack.
